Nearly 40 men at the office signed up to grow mustaches through November as part of a team registered at Movember.com, a global charity raising funds and awareness to combat prostate and testicular cancer.

Sgt. Jeff Byrne has “never grown a mustache,” so who knows what’s going to happen.

Some of the participants, however, are good at growing facial hair, so shaving all of it off Friday in preparation for the 30-day challenge was no big deal.

“It’s a good cause,” said Derek Conlon, a Mesa County information technology employee assigned to the Sheriff’s Office. Conlon’s goatee had been with him since he was a teenager. Oh well, he said, “Hair grows back.”

Lewis is the man behind the “Stash House” team. He heard about the website through his brother-in-law and thought growing mustaches sounded like a fun way to build camaraderie, and, more importantly, show support for Investigator Craig Tyer, who’s younger brother died of prostate cancer in February.

Plus, the losers — those who break down and shave this month — have to buy lunch for the men who don’t bail on the challenge, Lewis said.

He admitted he was “shocked” at how many men agreed to be on the team.
